Texas, lnneinvented certain new and useful Improvementsin DiskCultivators; and I do hereby declare the following to be a full, clear,"and exact, description of the invention, such aslwill enable othersskilled in the art it appe amslt'ol make and use the to wh c Thisinvention relates [to disk cultivators and particularly th'ose'of thesulky type.

The object oftheinvention resides in the provision of'a tan tor of thetype named in which the supporting wheels may be adjusted so' 'as"toibe'disposed differentdistances apart and in which the cultivating disks canbe adjusted with ease and facility both in vertical and horizontalplanes.

With the above and other objects in view the invention consists in thedetails'of construction and in the arrangement and combination of partsto be hereinafter more fully described and-particularly pointed out inthe appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views. and in which *igute l is aplan view of a disk cultivator constructed in accordance with theinvention; Fig. '2. a side view of same; Fig. 3, a rear view of theinvention; Fig. l, a front view of a fragment of the'cultivator; Fig. 5,a section on the line 5 of Fig. 1, and Fig. 6. a section on the line 66of Fig. 3.

Referring to the drawings the cultivator is shown as comprising an axle10 having a central arch portion 11. Adjustably mounted on the axle 10on opposite sides of the arch portion 11 are traction wheels 12respectively. said traction wheels being adapted to be adjusted toeither the full line position or the dotted line position in Fig. 1.Rigidlv mounted upon the arch portion 11 is draft tongue 13 which isconnected by braces ll with the axle 10. the rear end of said bracesbeing secured to the axle 10 adiacent the lower ends of the arch portion1-1. Connected to the horizontal port-ions of the axle 10 are arms 15which have fixedly secured to their free ends a shield 16 of the usualand well known construction- Se- Specification of Letters Yatent.

axle 10 and transversely of said tongue is a bar 17 and depending fromthelends of this bar respectively are armslS, the lower ends of saidarms being connected to the axle 10 by means or links 19. Carr ed byeacharm 18 is a syvingle tree-20 whereby the desired draft animals may beattached. Depending from the draft t'ongue'13 and secured to re-'spective sides thereof are bars 21 which have secured to their lowerends laterally directed v knives'22 which serve to cuttheweeds duringthe operation of the machine. Pivotally mounted on the axle 10 oneach-side of the a arch portion 11 is a u shaped'member A includingfront and rear arms 23-an-d 2431131 The upper end of the front armspectively. 23 of each U-shaped member terminates in a toothed segmentRotatably mounted of each member A' is a shaft 26 which has fixed on theforward end thereof a lever 27 whereby said shaft maybe rotated. Thislever 2-7 carries'a .spring pawl 28 adapted to posed in overlyingrelation with respect to the transverse arm of the other section andboth of the arms 32 are provided with openings 38 whereby the width ofthe arch mem ber B may be varied as desired, the sections of the archmember being secured against relative movement by bolts 34 passedthrough registering openings 33. The rear end" of each shaft 26terminates in a bearing 35 disposed atright angles to the longitudinalaxis of said shaft and having journaled therein a shaft 36. F ixed onthe upper end of each shaft 36 is a lever 37 carrying a spring pawl 38adapted to cooperate with a toothed segment 39 formed integral with thebearing 35. Formed on the lower end of each shaft 36 is in the arms 23and 24 rml a U-shaped frame 40 the. arms of which carry bearings 41rotatably supporting a adjusted in a vertical plane. while operation ofthe lever 13.7, will adjust the cultivating disk in a horiyontal plane.'It will be further apparent that by removing the vU-shaped members Afrom the axle 10 and then removing-the wheels 1*. these parts can bereplaced upon the axle with the wheels 12 in the dotted line positionshown in Fig, 1. Pivotallv mounted upon the tongue 13 is a lever llcarryinga spring pawl 45 which cooperates with a toothed segment it alsomounted upon'the tongue 1 are lower end of the lever l5 is connected tothe archmember l; by means of a link l7. while said arch member isconnected to the rear end of the shield 16 by means of a chain 48. Bymoving the upper end of the lever ll rearwardl v it will be obvious thatthe disk gangs will be elevated as will also the rear end of the shield1'5.

What is claimed is 1. A cultivator comprising anaxle. a U- shaped memberrotatably mounted on the axle. a shaft'journaledin the arms of saidU-shaped member. means for rotating" said shaft. a bearing on thercarend of said shaft. a vertical shaft rotatablv mounted in said bearing.nit-ans for rotating said vertical shaft. a u-shulwil nulrl er lixwl U!the verand a disk tical shaft, and adisk gang carried by the. U-shapedmember.

2. A cultivator comprising an axle having anal-ch central portion. adraft tongue secured to'said arch portion, a U-shapecl memnecting theshafts journa led inthe U-shapecl members. a lever pivoted on thetongue. connections between said lever and the arch member whereby themovement of said lever will swing the arch member to rotate the U-shapcdmembers on the axle. a bearing on the rear end of each shaft. verticalshafts rotatably mounted in each of said bearings,

means for rotating: each vertical shaft. a U- shaped member fixed oneach vertical shaft. gangcarried by the U-sha ped member.

In testimony whereof. I altix my signature. in the presence of twowitnesses.
